Purple Team Strategies

By: David Routin, Simon Thoores, Samuel Rossier

Overview of this book

With small to large companies focusing on hardening their security systems, the term "purple team" has gained a lot of traction over the last couple of years. Purple teams represent a group of individuals responsible for securing an organization’s environment using both red team and blue team testing and integration – if you’re ready to join or advance their ranks, then this book is for you. Purple Team Strategies will get you up and running with the exact strategies and techniques used by purple teamers to implement and then maintain a robust environment. You’ll start with planning and prioritizing adversary emulation, and explore concepts around building a purple team infrastructure as well as simulating and defending against the most trendy ATT&CK tactics. You’ll also dive into performing assessments and continuous testing with breach and attack simulations. Once you’ve covered the fundamentals, you'll also learn tips and tricks to improve the overall maturity of your purple teaming capabilities along with measuring success with KPIs and reporting. With the help of real-world use cases and examples, by the end of this book, you'll be able to integrate the best of both sides: red team tactics and blue team security measures.

Execution

This part of the ATT&CK framework is when an attacker already has some foothold in a network. For example, the victim has opened a malicious attachment that's been received by email and is moving their mouse to click on execute macros, or when attackers have sent a payload to a vulnerable server and the payload is being processed by the engine before sending the shell back to the threat actor.

This phase will occur when malicious code needs to be executed again and again until the attacker has reached their objectives. The famous motto from SANS, Malware can hide but it must run, illustrates these techniques perfectly. We will start by looking at built-in methods as they represent the simplest and fastest way to run code.

T1059 – Command and scripting interpreter

The easiest way to interact with a remote host is to use the tools that are already installed. This is why so many malware and attacks rely on the usage of built-in interpreters. Most of...
